More information wanted on LC/USGS MOU to inventory, scan, and archive USGS maps

Colleagues, I shared the following portion of the latest base line with a geological survey friend:

The Library of Congress and the U. S. Geological Surveysigned a Memorandum of Understanding July 25 to inventory, scan, and archivethe 210,000 USGS maps (1879-present) that are held by the USGS Library and theGeography and Map Division, and to disseminate the geospatial data developedpursuant to the USGS National Geospatial Program.

He had not heard about it and wanted to know more. Can anyone add to this information? I'll pass anything on to him.
